[PATCH] genirq: cleanup: no_irq_type cleanups
Clean up no_irq_type: share the NOP functions where possible, and properly name the ack_bad() function. Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
